Mitsubishi has launched it’s Ultra Quiet Ecodan range of Air Source Heat Pumps – offering efficient, reliable heating with greater flexibility in where they can be installed.
What is an Air Source Heat Pump?
An Air Source Heat Pump is electrically driven and utilises a refrigerant cycle, similar to a Ground Source Heat Pump but extracting heat from the air. This heat from the air is absorbed at low temperatures into a fluid inside specially installed pipes. The fluid then passes through a compressor which raises it to a higher temperature, ready to be delivered to your heating and hot water systems.
Heat pumps are not really ‘noisy’
Quite often the very first question people will ask us when discussing a renewable solution for their project is “are air source heat pumps noisy?” The reality is that whilst some early heat pumps were found to be noisy, modern units are often quieter than the flue of an oil boiler and the Mitsubishi Ecodan unit already comes assured with the QuietMark.
The Quiet Mark is a badge of approval awarded by the Noise Abatement Society to manufacturers of the quietest products currently available, and is validated by the Association of Noise Consultants.
In January 2012, Mitsubishi Electric’s range of Ecodan air source heat pumps were the first air source heat pumps to receive the official backing of the Noise Abatement Society, being awarded the ‘Quiet Mark’ of approval.
The new Ultra Quiet Ecodan
The latest innovation from Mitsubishi takes things even further. The Ultra Quiet Ecodan is available in 8.5kW and 11.2kW sizes and is designed specifically for UK residential use with a 8 db (A) drop in sound power, enabling almost any home to benefit from high performance, renewable heating.
Max Halliwell, Product Manager for renewable heating systems, said: “The government has already recognised how important air source heat pumps will be for the future of low carbon heating in the UK and is forecasting one million sales a year by 2030.
“One of the key areas that will affect adoption of these energy-saving systems is noise, which is why Permitted Development exists, and these new units are designed specifically to overcome any issues with noise.”
To ensure neighbours are not disturbed, Permitted Development requires sound levels to meet certain limitations, with the sound pressure level not exceeding 42 decibels, dB(A) when measured at a point one metre away from the neighbour’s nearest door or window.
Halliwell added: “Our market leading Ecodan heat pumps have always been amongst the quietest on the market and are designed to provide any home with reliable, trouble-free renewable heating and hot water. New Ultra Quiet Ecodan takes this to the next level with low sound and high performance which mean homeowners can now choose the most convenient location for their heat pump, giving complete flexibility on placement and still meeting Permitted Development requirements.”
Sound power can be thought of as the cause of a noise or the total sound energy emitted by a source in all directions, whereas sound pressure is the effect or the sound we hear and this is determined by the environment and by the distance from the source of sound. We think of this as the intensity or loudness of a sound. A jet plane registers around 120 dB(A) whereas your alarm clock around 70-80 dB(A) and your dishwasher at around 50-60db (A).
“With a sound pressure level of just 45 dB(A), the new Ecodan is whisper-quiet, with levels just above that of a library, meaning it will pass the Permitted Development requirements easily and can be installed almost anywhere to suit the homeowner,” explains Halliwell.
Innovations in fan and compressor design have enabled the units to achieve such low levels of sound whilst increasing performance and efficiency.
